GIP is much the same as SMPP - it was invented by a guy who works here. It
would be quite cool to have an open implementation of SMPP and also the CMG
version called EMI.

No, there's no need to go near c7 if all you want to do is send and receive
SMSs via an exsisting SMSC. Making this sort of service is quite easy - we
have several such SMS related services including Welcome SMS and a
distribution lists service
(http://www.t-mobile.co.uk/Dispatcher?menuid=phones_tfe_tm_gt) live in our
Network using GIP.

No, Don't worry about that stuff.

Hope this is enough to at least point you in the right direction
